cAP AND PACKAGE.

Application filed March 23, 1925. Serial No. 17,477.

This invention relates to the art of packaging and particularly toaclosure cap and to a closed package.

The general object of the invention is ,to

provide a form of closure and container which will effectively cooperateto form aclosed package even with very wide var1a-' tions in the sizeand proportion of the container.

Another object of the invention is to provide a quick action closure ofincreased reliability and effectiveness.

A further object of the. invention is to provide a closure whichpossesses the adi vantages of both friction closures and screw closures.

A still further object of the,invention is to provide a sealed packagewhich can be readily and quickly opened, but which is positivelysafeguarded against accidental opening.

Other objects of the invention will be apparent fromthe followingdescription.

In accordance with the present invention there is provided a closurecap, preferably made of sheet metal or the like, which em-. bodies acover portion and a skirt portion. The skirt portion of the/cap isprovided with an impressed groove extendingi circumferentially of the s'irt and adapte to grasp the sidewall of a suitable container. This'circumferentially. extending groove may be smooth or it may be providedwith suitable corrugations or the like which increase its tion andthereby size the groove to the particular container to which the closuremay be applied. At the base of the skirt there are provided locking lugspreferably in the form of open coils rolled up within the skirt fromportions of metal integral therewith.

The closure is adapted to be applied to a container which has asubstantially cylindrical but discontinuous surface adjacent the mouththereof. This discontinuous cylindrical surface terminates in a seriesof downability to expand in a. circumferential direc-' the closure isapplied. The circumferential groove in the closure skirt grasps thecylindrical surface and functions to hold the closure frictionally uponthe container.

Fig. 1 of'the drawings is a perspective view showing a closure capembodying the present invention.

Fig. 2 is an elevational view partially in section showing a closedpackage embodying the cap of Fig. 1.

Fig. 3, is a plan view showing the mouth of the container shown in Fig.2.

Fig. 4 is an elevational view of a package embodying the presentinvention.

Fig. 5 is a sectional view of a modified form of closure embodying thepresent invention.

Fig. 6, is a sectional view showing another modified form of closureembodying the-present invention.

As shown more especially in Figs. 1 and 2 there is provided .a closurecap of sheet metal or the like having a cover port-ion 1, and a skirt 2provided with an inspun annular groove 3 which is adapted to grasp acylindrical surface 4 of a suitable container 5. By reason of the factthat the portion 3 is inspun, it forms a resilient groove which isadapted to be displaced outwardly when the closure is applied, to sizethe groove to the particular container. This groove maybe plain as shownin Fig. 4, but is preferably provided with a series of indentations orcorrugations, as shown in Fig. 1, which adapt it for very largecircumferential expansion and thereby enable the closure to take care ofwide variations in the size of the container finish.

At the base of the skirt 2, there are provided a series of locking lugsor projections 6, preferably in the form of large resilient coils, whichmay be rolled up within the skirt from strips of metal integraltherewith.

As shown particularly in Figs. 2 and 3, the container 5 is providedadjacent its mouth with a substantially cylindrical surface 4interrupted by discontinuities at 8. Each section of cylindrical surfaceat terminates in a locking shoulder 7 which is circumferentiallyinclined downwardly to form a cam surface. i

The closure is applied to the container by passing the locking lugs 6downwardly along the discontinuities 8' and then rotating the cup tocause the lugs 6 to cooperate with the cam surfaces 7, .and therebyexert an endwise clamping force upon the closure. When the closure isapplied the annular groove 3 grasps the cylindrical surface 4: in themanner of a friction retained closure. After the package has been sealedthe grip of groove 3 prevents movement of the cap not only verticallybut circumferentially,and thereby precludes the cap from beingaccidentally unscrewed due to the camming action between the camsurfaces 7 and locking lugs 6. If groove 3 is corrugated as shown inFig. 1 the corrugations engage the corners of the surface 4 at thediscontinuities 8,

:. thus securely holding the cap against rotation. This enables thecamsurfaces 7 to be made very steep without any danger of the cap becomingunscrewed due to 'cammlng action.

The cap may be formed with a dome like cover portion as shown in Fig. 1,or it may be formed with a fiat cover portion as shown in Fig. 5, orwith a depressed cover portion as shown in Fig. 6.

As shown in Figs. 2, 5, and 6, there is an annular recess 9 adjacentthecover portion which serves as a means for retaining a suitable gasket 10in the closure and thus enabling the cap and gasket to be applied to thecontainer in a single operation. The gasket 10 may be in the form of acomplete disc as shown in Fig. 5, or in the form of a ring as shown inFig. 6. The ring form of gasket is particularly suited to the form ofclosure shown in Fig. 6, since it seats in the annular recess betweenthe skirt and the depressed portion of the cover.

It is seen that the present invention provides a quick acting closurewhich is very reliable and effective on account of the fact that itincorporates the holding powers of both a friction retained closure anda screw closure. It is also apparent that'the present closure may beapplied and removed by rotation through a com aratively small angle; andthat after app ication the closure is positively safeguarded againstaccidental unscrewing. v

It is realized that the present invention may be embodied in forms otherthan those particularly disclosed and hence it is desired that thedisclosure be considered as illustrative and not' as limiting.

Having, thus described my invention,

' what I claim is 1. A package comprising a container having aninterrupted substantially cylindrical surface adjacent the 'mouththereof and locking shoulders beneath the cylindrical surface; incombination with a closure hav-. ing a skirt provided with acircumferential groove grasping said interrupted cylindrical surface andlocking projections cooperating with said locking shoulders.

2. A package comprising a container -rupted cylindrical surface andhaving an interrupted substantially cylindrical surface adjacent themouth thereof and cam surfaces beneath the cylindrical surface; incombination with a closure having a skirt provided with acircumferential groove grasping said interrupted cylindrical surface andlocking projections cooperating with said'cam surfaces to exert anendwise ing an interrupted substantially cylindrical.

surface adjacent the mouth thereof and inclined locking shouldersbeneath the cylindrical surface; in combination with a 010-" surecomprising a skirt provided with a resilient circumferential groovegrasping said interrupted cylindrical surface, and resilient open rolledlocking projections cooperating with the inclined locking shoulders toexert a yielding endwise clamping force on said closure.

5. A package comprising a container having an interrupted substantiallycylindrical surface adjacent the mouth thereof and looking shouldersbeneath the cylindrical surface; in combination with a closurecomprising a skirt provided with a circumferential groove grasping saidinterrupted cylindrical surface, and lockingprojections cooperating withsaid locking shoulders, said closure being adapted to be removed byrotation of the closure locking projections into alignment with thediscontinuities in the cylindrical surface and then withdrawing thelocking projections along the. discontinuities.

6. A package comprising a container hav: ing an interruptedsubstantially cylindrical surface adjacent the mouth thereofand lockingshoulders beneath said surface; a gasket in contact with the mouth ofsaid container; and a closure cooperating with said gasket, said closurehaving a skirt provided with a circumferential groove graspin saidinterlocking projiections cooperating with said locking shoulers.
